You're so right. I teach in a farming community. We have lots of migrant workers, and their kids live such hard lives. Years ago, the kids would be up before sunrise picking apples with their parents for a couple of hours before coming to school! That seems to have stopped, thank God.
But still, there's the fear of being deported (yes, the parents are pretty much ALL illegal). And then the money situation. These kids - and their parents - appreciate everything.
One year, I had a little girl with 4 big brothers. All of her clothes were hand-me-downs from the boys because her parents didn't want to accept charity. She told us that she wanted Santa to bring her GIRL's underwear!

So, at Christmas, my friend and I not only bought her 2 packages of frilly Barbie panties, but we also bought her girly-girl pajamas, a girly party dress and black patent-leather shoes, along with a few other girly outfits. What a difference it made in her entire attitude when she came to school!!!
That's why I love teaching. We really do make a difference!!
